What this category of data looks like
Data originates from oilfield engineering service operation records, process specifications, on-site feedback documents, and historical inquiry ledgers from service windows. Updates occur immediately after a single project is completed and archived, or via monthly batch synchronization of all valid documents. Most individual documents mix structured and semi-structured content. Fields include operation numbers, construction locations, technical parameters with units such as pressure and displacement, approval nodes, and inquiry item categories. Some long documents contain multi-page construction steps and compliance requirements.
Constraints on model access and configuration
Oilfield engineering service documents contain many technical parameters with units and structured operation processes. Models must retain unit and field integrity during retrieval and generation. The mixed structure of multiple document types requires distinguishing retrieval weights for technical parameter content and business process content. Documents updated immediately after project completion require the knowledge base synchronization cycle to align with operation rhythms, to prevent outdated data from being used for inquiry responses. The high proportion of long documents requires reserving sufficient space in context configuration to cover complete operation link information, avoiding truncation of key content.
Configuration settings
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
maxContext | 8000–12000 token | Oilfield engineering documents are mostly long texts, requiring coverage of complete operation processes and parameter information to avoid truncation of key content |
temperature | 0.1–0.3 | Service inquiries and technical replies require precision and accuracy, and content deviating from facts should be avoided |
quoteMaxToken | 2000–3000 characters | Complete quoted content including technical parameters with units and approval nodes must be retained |
toolChoice | auto | Automatically select whether to call the knowledge base or tools based on inquiry content, adapting to different scenarios of process inquiries and technical parameter queries |
AIPROXY_API_ENDPOINT | Exclusive API address of the deployment node | Ensure requests are routed to the specified model service and avoid cross-region latency |
AIPROXY_API_TOKEN | Token bound with exclusive permissions | Restrict access scope and ensure the security of internal oilfield data |
Three common configuration mistakes
- Issue: Duplicate configuration of the Qwen/Qwen3-Embedding-8B model overwrites the original configuration and causes knowledge base index failure. Cause: FastGPT’s model configuration mechanism uses the model name as the default unique identifier, and no additional identifier is provided to distinguish configurations of the same name but different instances.
- Issue: After the large model calls the knowledge base, output content includes the phrase "Citation: [1]". Cause: The automatic citation marker generation logic was not disabled during configuration, or correct output format filtering rules were not configured.
- Issue: Markdown format parsing errors occur when importing oilfield engineering documents to build a knowledge base. Cause: Imported documents contain unescaped special characters, or chunking configurations do not adapt to the markdown structure of long texts, leading to parsing errors.
How to verify a successful configuration
- Submit a test inquiry that includes oilfield technical parameters, and confirm the output retains parameter units and complete quoted information.
- View model call logs in FastGPT v4.17.0, confirm requests are routed to the configured
AIPROXY_API_ENDPOINTaddress, and token verification status is normal. - Import a single long document for testing, check that the context configuration covers the full content, with no key information truncated.
- Attempt to add a duplicate-named model configuration, check for an overwrite prompt or an option to retain multiple instances, to verify the model configuration mechanism behaves as expected.
